Enclosure Fan Heaters

Item# CR2700900

Enclosure Fan Heaters Enclosure Fan Heaters
An easy DIN rail mountable design makes the CR027 Series fan heater an ideal accessory for any enclosure. The CR027 maintains minimum operating temperatures in enclosures and helps to prevent failure of electronic components caused by condensation and corrosion.

To determine the required heater size follow this equation:

PH = (A x ΔT x k) - Pv
    PH = Required heating power for your application in Watts (W)
    Pv = Heating power generated by existing components (e.g. a transformer) in Watts (W)
    A = Exposed enclosure surface area square meters (m2)
    ΔT = Temperature differential between the desired minimum interior temperature and lowest possible external temperature of the enclosure in Kelvin (K), 1.8°F = 1°C = 1K
    k = Heat transmission coefficient of the enclosure material used:
       &nbspStainless Steel: 3.7 W/m2K
       &nbspPainted Steel: 5.5 W/m2K
       &nbspAluminum: 12 W/m2K
       &nbspPolyester/Plastic: 3.5 W/m2K
For outdoor applications it is recommended to double the heating power.
